The EMP cortically induced current in coaxial cables near the ground is analysed by using Finite-Difference Time-Domain method in this paper. 本文采用时域有限差分法，分析电磁脉冲作用下，地面附近同轴电缆所感应的外皮电流。
The effect of waveguide width on the propagation of self-collimated beams in photonic crystals is studied using the finite-difference time-domain method. 在此基础上，运用时域有限差分法对自校准光束在有限宽的波导中的传播行为进行了定量研究。
